From: Arnd Bergmann
Date: Mon Mar 04 2019 - 14:53:52 EST


drivers/gpu/host1x/hw/channel_hw.c: In function 'host1x_channel_set_streamid':
drivers/gpu/host1x/hw/channel_hw.c:118:30: error: implicit declaration of function 'dev_iommu_fwspec_get'; did you mean 'iommu_fwspec_free'? [-Werror=implicit-function-declaration]
struct iommu_fwspec *spec = dev_iommu_fwspec_get(channel->dev->parent);
^~~~~~~~~~~~~~~~~~~~
iommu_fwspec_free
drivers/gpu/host1x/hw/channel_hw.c:118:30: error: initialization of 'struct iommu_fwspec *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion]
drivers/gpu/host1x/hw/channel_hw.c:119:23: error: 'struct iommu_fwspec' has no member named 'ids'
u32 sid = spec ? spec->ids[0] & 0xffff : 0x7f;
